On historicity of Jesus

I have been reading Albert Schweitzer’s autobiography and in there he talks about his book the quest for historical Jesus which if you have not read yet, I suggest you do. But that’s not what caught my eye. He mentions the works of J. M Robertson, William Benjamin Smith, James George Frazer, Arthur Drews as those who have contested the historical existence of Jesus.

He writes

It is not difficult to pretend that Jesus never lived. The attempt to prove it, however, invariably produces the opposite conclusion. In the Jewish literature of the first century the existence of Jesus is not attested to with any certainty, and in the Greek and Latin literature of the same period there is no evidence for it at all. Of the two passages in his Antiquities in which the Jewish writer Joseph’s makes incidental mention of Jesus one was undoubtedly interpolated by Christian copycats.[…. ] It still has to be explained when, where and how Christianity originated without either Jesus or paul; how it later came to trace its origins back to these mythical personalities; and finally for what curious reasons they, both Jewish, were designated as the founders of Christianity. To prove that the gospels and epistles are not genuine one has to explain how they were written without being authentic.

Out of my life and thought: an autobiography
